Nebraska Beef Cattle Reports

Summary with Implications

This study evaluated the impact of high-pressure processing (HPP) on color, oxidative stability, and tenderness of tenderloins (psoas major) from cull cows to determine if HPP could enhance their marketability. Forty cull cow tenderloins were treated at two different HPP pressures and two different holding times, then assessed for instrumental and visual color, lipid oxidation, and Warner-Bratzler shear force during a 7-day stimulated shelf period. HPP increased initial lightness, especially at the highest pressure and longest holding time and improved redness initially. However, redness declined, and discoloration increased over the 7-day period, particularly after processing at higher …

Using High-Pressure Processing To Improve Dark-Cutting Beef Color In Tenderloins, Ashley A. Hahn, Leila G. Venzor, Shelley A. Curry, Grace C. Johnson, Mary-Grace C. Danao, Ranjith Ramanathan, Gary A. Sullivan, Jordan C. Wicks

Nebraska Beef Cattle Reports

Summary with Implications

Dark-cutting beef is a quality defect that negatively impacts consumer appeal and affects the carcass value for both producers and meat processors. These economic losses stem from poor visual appearance and reduced consumer appeal in the retail setting. Notably, different muscles within a carcass exhibit varying degrees of color stability which can influence how dark-cutting manifests across cuts. Therefore, this study aimed to examine the effect of high-pressure processing (HPP) on dark-cutting color-labile muscle. Dark-cutting and normal tenderloins were collected and portioned into two equal sections. Dark-cutting tenderloins were assigned one of 3 treatments: No HPP, 300 …

Nebraska Beef Cattle Reports

Summary with Implications

Dark-cutting beef is a result of preharvest stress and devalues the resulting carcass. High-pressure processing (HPP) has been recently identified as a potential strategy to improve the undesirable appearance of dark-cutting beef. Dark-cutting beef strip loins were collected from a local processing facility, sectioned, and assigned an HPP pressure (300 or 450 MPa) and holding time (0, 1, 30, 60, or 90 s). Overall, HPP increased the lightness and redness of dark-cutting beef, particularly the longer the pressure was held at both pressure levels. Additionally, negative effects such as increased meat discoloration, decreased tenderness, and increased rancidity …

Dietary Supplementation In Lambs: Evaluating The Effects Of Depth Charge On Meat Composition, Alianna Koesel

Student Scholar Symposium

Often, animals destined for consumption are fed supplements to help speed up or slow down their growth rate, enhance aesthetics, or standardize the product. Herein, we examined the supplement Depth Charge and its effects on the fat and protein content in lambs of the same age and lineage. Depth Charge increases fiber consumption to add spring of rib or an outward rib cage curvature to an animal's appearance while restricting feed consumption. Since the supplement targets the rib-loin area, we chose to analyze loin chop, loin roast, and hamburger cuts from each lamb and conducted experiments to determine how each …
